To all whoml t nitty concern.:

Be it known that. I, Jisivzvixos CROP'PER WISE, a citizen of the United States, and a4 tion are the. following: firstl a comparatively l large. capacity for a given area occupied hy i tion of a richer i third. perfect coinjects upwardly.

the burner; second. the produc -and more uniform gas bustion of the-sulfur known upon the market "ats""L-ouisiana"` sulfur: fourth. a saving of labor. due to the fac-t that the movement of the-.sulfur into the, pot is l l and is mounted wit-hin a pedestal 17 being i mounted rigid-l)T upon the inner end of the shaft` 9 and rotates therewith.- A bevehgear 14 meshes with the .bevel-pinion 13 and is provided with a shoulder 15, which encirclcs a stcni 16. The latter is preferably of steel secured rigidlyY therein-by a set-screw 1S. The up )er end of the edestal 17 terminates in a ball-hearing 19, w uch engages the lower center portion'of the shoulder 15, so that. the bevekgear 14 virtuallv turns upon the ballhearing. Integral with the bevel-gear 14 and shoulder is a barrel 2U. which encircles the stein 16 and is free to turnthereuponI Integral with the ot T and encircling the barrel 2O is a bearing-sleeve 21, which pro-l An annular head 22 is secured rigidly to the. upper end of the barrel to some extent autoniatic-.z fifth, ease of regulation of the adniission of air, and. sixth. uniformity of adnus- 'represented h v the stein 16, the tooth 24 sion of air into different parts of the. liurner.'

I accomplish these iesults by certain mechanism drawings. described below, and pointed out in the appended claims.

Reference is to he had to the accompanying drawings. forming tion, in which similar characters of reference indicate corresponding parts in all the iigures.

These arms are provided. respectively. with teeth .24 25, disposed a. equal distances roni the center being soI disposed relatively to the tooth .25 as to sweep through dilei'ent )a-ths-that is to say. a4 tooth 25 does notv follow the saine path as a tooth 24. The purpose of this arrangement is to render the stirring more thorough.

The pot T is provided with av circular ay erture 26. normally closed by a circular t oor Figure 1 is a side elevation of my huriier complete. including the driving mechanism.

Upon afsurface 5 restpedestals 6, supporting a pot- 7, the general forni of which is circular. De ending from this ot 7 are hangers 8, ti-hic support a rotatale shaft 9, the outer 'end of is provided with a -sprocketwheel 10, suitable for a. chaindrive, whereby-the shaft is rot-ated. Collars 11 12 V"Intunijaiin the4 in pro er working relashaft tiring@ the hangers 8. evel-pinion 13 is 'l Disposed upon opposite sides of this door are lugs 2S. supporting avr link 39 and iy means of pins 30. A screw 31 passes vertically through the link 29 and is provided with a head 3:2, through which passes a hand-lever This arrangement is quite analogous to that einploj'ed upon a copying-press. By turning the handlever 33 the screw 31 is caused to rotate, and the plate 2 of thepotV 7 or is released therefrom, accordinfr to the direction of rotation of the screw. W en the screw is so 'turned as to lower the platefl. the latter rests upon the upper side of the link 29. The arrangement just. described is for the piu'pose of enabling residual substances and impurities to pass from the pot. Thest-iireis being constantly at work and the sulfur being gradually burned out, all residual substances raduaily assume the forinof a powder and id lodgnient within t 2 his scribed ,1 the i for instance,

T is forced against the under side .ga-tes 35.

neath the pot 7, so as to scrap the upper surface ot the late 27;v The pot 7 is further provided wit horizontally-disposed slots 34, and adjacent to each slot is a movable gate 35, which lits in slideways 36 in verticallydisposed lugs 37. Threaded through each of these lugs for the purpose of holding it in position is a bolt 38, having upon its lower end a revoluble nut 39. The lugs 37 may be removed by merely loosening the nuts 39 and 'taking out the bolts 38. Each gate 35 is provided with handles 40, whereby it may be raised or lowered, and the gate fits into. its slideways with such a degree of tightness that the operator by merelv pushing it up or down regulates the virtual capacity or size of the corresponding'slot 34.

A flange 41` servesv as a limiting-stop for the If the slots 34 are to be entirely closed, the gates 35 are merely pushed. down into engagement with the ilange 41. Ano-ther Han e 42 is abovethe ange 41, and engaging the flange 42 is al flange 43, which is integral with a dome 44. A

A lnumber of feed-holes through the'pot are shown at.45 and are spaced equisdistant. Ad'acent to each of these feed-holes is a conica. valve 46, mounted rigidly u on the end of a revoluble screw 47, provide at its outer" end with a hand-wheel A48. By turning the hand-Wheel 48 the conical valve 46 is brought partially into't'he corresponding feedhole-45 and may be made to close the-same to any desired extent. In order, therefore, to regnlate the capacity of the feed-holes, all that is necessary is to turn the h andswheel 4 8.

The dome 44 is'provided with a neck 49, terminating in a flange 50,.-which engages a flange 51 of another neck 52. Mounted upon the neck lastmenti'oned is a combustion-box 53. The latter is of cylindrical shape and is provided with slideways 54. The ends of the combustion-box 53v are disks or heads 55, each being rovided with a s id-er 56, supporting a revruble damper 57. y turning this damper the interior of the combustion-box may to a greater or lesser extent be brought into communication with the outer atmosphere. Bolts 58 59 secure one of the heads in position. The other headis mounted upon a hinge 6() and bolts 59. By removing the latter this head (represented at the rig-ht of Fig. 4) may be swung open.

Mounted in slideways 54 and inclosed by the combustion-,box 53 is a baille-plate 61, provid-ed at its o posite ends withapertures 62, as will be un( erstood fromFi 4. This balflefpla-te maybe removed by sliding it out endwise, one zor the other of the heads 55, preferabl the one'shown at the right of Fig. 4, being rst moved out of the way. VDoors 63, mounted upon hinges 64, are employed for 4the purpose of giving yaccess to located some distancel the aperture 26, as

. gentral the interior of the apparatus. Super osed above the combustion-box 53 is a nec 65, and adjustably mounted within this neck is a damper 66, supported by a stem 67. By turning the latter by hand the damper 66 may be tilted to any desired angle, and thus caused to 'check the outflow of gas from the burner. The neck 65 terminates in a flange 68 for enabling the apparatus to be connected with a cooler of the style commonly used in this art. AA hopper is shown at 69 and is used for supplying sulfur to thepot.

The o eration of myndevice is as follows: Sulfur o almost any kindfor instance, thev so-called Louisiana sulfur-is placed Within the hopper 69 and is melted by heat from the interior of the pot, as hereinafter described. The molten sulfur seeks to find-s its Way throu h the feed-holes 45, and the capacity of tliese holes, as above explained, is regulated by turning the hand-wheel 48 into appropriate position. The sulfur is thus gradually fed down into the pot, Where it :appears as a liquid. Power being now applied to the sprocket-wheel 1.0, the stirrer 23 1s rotated and the teeth 24 25 pass circularly around the bearing-.sleeve2L 'Aseaehtoot describes a path 1ndependent of the other ypath the stirring is rendered thorough. After a long use .any residual powder which may accumulate in the pot is removed throu h. above described. T e sulfur within the pot is ignited and tends to burn after the manner of otherfcombustibles. The supply of air throu h the slots 34 is `regulated to a nicety by a justing thepositions of the several Agates 35. The exact position to be occupied by these gates in order to supply a proper degree of airis somewhat arbitrary, depending upon 'the qaulity of the sulfur, the temperature ofthe air where' the apparatus is being used, .the size of the apparatus, the force exerted by the suction-pump in draw-ing gases out of the apparatus, and many other Jfactors. AThe .quantity of air supplied to the burning sulfur is such as to form sulfur dioxid, (SO2). which isemployed in making sult liquor. As the gas lpasses upward 1n the combustion-box 53 1t encounters the baffle-plate 6l and is forced to divide so as to pass through the two apertures 62, as will be understood from Fig: 4. The two portions of gas thus separated im mediately recombine 1n the upper part yof the combustion-chamber. The dempers 57 'if turned to a proper angle admit sufficient -ai-r to prevent sublimation. I find thati-n seme instances it is desirable -t-o admi-t a sipply of air directl inthe combustion-'box ign ependently of t e supply of air through the'slots' 34. It is upon -this account 'that vI em ley the two dempers 57. By tui'rng these amlpers to any desired extent acorrespondmg amount of air is caused -to enter through the heads of the con-ibustion-boac..V This auxilfl 4-ticuliir mecha msm showniary admission of air is desirable when for any reaso'n ditliculty is encountered in causing thorough combustion Within the pot, and conset uently there is a tendency for the iinburnei sulfur vapors or sublimed portions of the sulfur to pass off in elementary forni. I iid that. il air be admitted -through the heads of the combustion-boit, as above described, it will cause any uiibu'rned sulfur vapors or subliniated portions' of sulfur to burn and form SO2, provided\`the aeriforin portions just mentioned have"" sutlicieiit heat. It should be borne inmind that notwithstanding the endosmotic proportion of gases and vapors it may sometimes happen, especially in a rapidly-working apparatus, that some ortion of sulfur vapor does not happen to be brought into contact with a proportionate quantity of air, and while ossessing sufficient heat to support com ustion is prevented from being consumed upon this account. In such instance the auxiliar)v air` inlets are useful. The dampers and bafileplat'es are essential to thorough combustion` I desire to lay ein hasis upon 4the fact t-hat the general forni o lthe pot is circular and that the slots 34 are therefore arranged in the forni of a circle and are equidistant from the center of the ot. By this arrangement the several iistinct volumes of4 air passing inward radially ,through the ditl`erent slots toward the cent-er of the burner must travel equal distances and are therefore exposed to like conditions. The tendency, therefore, is to produce uniformity in the conditions existing throughout the potI and to roniote the uniform combustion of the su. ir'\'apor as far as practicable. I have found from act-ual trial that the circular t'o'rm given to the pot increases the general etliciency of the a ai'atus to a degree which isV astonishing. lille better results are, no doubt, attributable to the fact that perfect burning of the sulfur is obtained because of the equality of the several draf-ts taking place in different directions. Moreover, be-

cause of tlietact that the several drafts coni verge towartl the center of the pot the admixture of the cir and gas is rendered more thorough than would be the case if a cubular pot were employed. v

, The machine above described mayr be employed for many purposes other than that described. I therefore do not limit myself to any particular service to which it may be applied; neither dol limit myself to the par- Having thus described my invention, I claim as new and desire to secure by Letters Patent-fl.
